The stage electric hoist controller is a device used to control the operation of the stage electric hoist. The following is the relevant introduction: Classification by Control Method Wired Controller: It is connected to the electric hoist through a cable. Commonly, there is a push - button - type wired controller, which has buttons such as up, down, and stop. Operators control the actions of the electric hoist by pressing the corresponding buttons. There is also a joystick - type wired controller, which controls the running speed and direction of the electric hoist through different angles and positions of the joystick. It is often used in situations where more precise control is required. Wireless Controller: It uses radio signals to communicate with the electric hoist, getting rid of the bondage of cables, allowing operators to move and operate freely within a certain range. It generally consists of a transmitter and a receiver. The transmitter is similar to a remote control. The operator holds the transmitter and presses the buttons to send signals. The receiver is installed near the electric hoist, receives the signals, and controls the operation of the electric hoist. Classification by Functional Characteristics Single - control Controller: It can only control one electric hoist and is suitable for scenarios where only one electric hoist needs to be controlled separately, such as controlling the electric hoist for suspending a single lighting device on a small - scale stage. Group - control Controller: It can achieve synchronous control or individual control of multiple electric hoists. For example, on a large - scale stage, when multiple electric hoists are needed to lift or lower simultaneously to adjust the height of large - scale scenery or trusses, the group - control controller can be used for unified operation. It can also control a certain electric hoist individually as required. CNC Hoist Controller: For example, the fineline vsc3 (vector servo controller) axis controller in the fineline CNC hoist system of Guangzhou Colorful Firefly. Based on the object - control programming mode, it enables simple, intuitive, and efficient programming. It allows the construction of cues and the operation of various connection options, and can achieve quick setting, real - time feedback, and remote configuration. Common Components Operation Components: Such as buttons, joysticks, touchscreens, etc., are used for operators to input control commands. The touchscreen can display information such as the running status of the electric hoist and parameter settings, and various controls and settings can also be carried out through touch operations. Control Circuit: It includes logic programmers, inverters, etc., which are used to process the signals input by the operation components and convert the signals into commands for controlling the motor of the electric hoist, realizing the control of the speed, direction, etc. of the electric hoist. Safety Protection Components: There are emergency stop buttons, overload protection devices, limit switches, etc. The emergency stop button can cut off the power immediately in an emergency and stop the operation of the electric hoist. When the load borne by the electric hoist exceeds the set value, the overload protection device will automatically stop the operation to prevent equipment damage due to overloading or the occurrence of safety accidents. The limit switch can limit the upward and downward travel of the electric hoist to avoid exceeding the safe range.

Power Components: They provide power for the controller and the electric hoist, including power distribution units, circuit breakers, etc., to ensure the stable and safe power supply.
